Up sh*t creek...

God I don't know why I opened this thread on a Friday night. We have some apartments with access panels over stacks with rubber couplings because they get clogged so often. Clogs suck and that's the bottom line. You can run snake through every drain in your house and it's always the last one. Boring dirty work. Turn on all faucets in the house and let them run. First one to back up is where I would focus at first.
